One sprinkler zone drizzling when system is off

Today is an OFF day for our sprinkler system. By chance I discovered that all zone 2 sprinklers were drizzling (meaning very small amount) of water. I went to the master control panel and switched the system off. Even with the system manually switched off all zone 2 sprinklers continued to drizzle. I was forced to turn off the incoming water at the sprinkler system valve. Of course that action stopped the zone 2 drizzle.

The valve to zone 2 more then likely has contamination inside (internally) and has now fauled up the valve.

Locate
the valve in question and take it apart- inspect the diaphram for
damage and flush the valve. Recommend to replace the diaphram.

Where abouts do you live?

DeSoto, Tx, a suburb of Dallas. I will get a sprinkler company to do the repair. In years past I would do it myself but now I have only one usable arm making digging quite a challenge. Btw, where is the zone 2 valve located.
